Study Notes
Understanding Physical Changes
- Refers to alterations in the body that do not change chemical composition, such as growth in height or changes in body shape.
- Includes modifications in skin texture, hair growth, and increase in body mass.
Stages of Prominent Physical Changes
- Most significant during puberty, which typically occurs between ages 9 to 14 for females and 10 to 15 for males.
- Associated with hormonal changes that trigger growth spurts and development of secondary sexual characteristics.
Influential Factors in Physical Changes
- Least likely to be influenced by external environment or social factors; genetics plays a predominant role.
- Individual differences stem from hereditary information, rather than lifestyle choices or socio-economic status.
Common Physical Changes from Childhood to Adulthood
- Growth spurts leading to increased height and muscle mass are commonly observed.
- Development of secondary sexual characteristics, such as breast development in females and voice deepening in males.
Focus of Studying Physical Changes
- Emphasis on understanding how physical maturation impacts individual development and psychological growth.
- Observations on how these changes affect emotional well-being, social dynamics, and self-image during transitions into adulthood.
Growth Spurt
- Height and weight increase significantly during puberty.
- Growth spurt typically occurs between ages 9-14 in girls and 10-16 in boys.
